Stenocarpus villosus is endemic to New Caledonia, restricted to the southern east coast of Grande Terre. It is found in shrubland on ultramafic substrate between 490 and 536 m asl. Known from three locations, its extent of occurrence (EOO) and area of occupancy (AOO) are estimated to 283 and 12 km², respectively. The main threats are uncontrolled bushfires and mining activities. The Ouinnée's subpopulation which occurs in the mining exploitation area can be directly affected. Therefore, S. villosus is listed as Endangered (EN) under criteria B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v).

Geographical area


S. villosus is endemic to New Caledonia, where it is restricted to the southern east coast of Grande Terre: Kouaoua and Ouinné.

Population


Population size is unknown.

Habitat


S. villosus occurs in shrubland on ultramafic substrate between 490 and 536 m asl.

Threats


The main threats are posed by uncontrolled bushfires and mining activities at Ouinné (SMGM).

Conservation


S. villosus is protected by legislation in New Caledonia but does not occur in any protected areas. This species would benefit from ex situ and in situ emergency conservation actions. It is recommended to monitor and preserve known populations in delimited areas of the mining site, and to inform the local authority responsible for the coordination of the firefighting effort about the presence of the species in the concerned areas. It would also be advised to run multiplication tests in order to assist future planting operations. Finally, prospection at Ouinné and Boakaine is needed to better estimate the size of the population and understand potential threats.
